Get more error messages from mssql.dll

[aCa]

Hi. Im trying to get some more error messages from the mssql.dll. I somtimes get the error message "Unable to connect to server: servername". I would like to get an error message or error code from the database driver instead of the error message hard coded in the php_mssql.dll.

My problem is that I dont know C very well. There is two places in the php_mssql.c file where that error message can come from. The two places are the same the only diffrence is that one if for the persistant connection the other one the regular conect.

if ((mssql.link = dbopen(mssql.login, host)) == FAIL) {
	php_error_docref(NULL TSRMLS_CC, E_WARNING, "Unable to connect to server:  %s", host);
	efree(hashed_details);
	dbfreelogin(mssql.login);
	RETURN_FALSE;
}

I would like to be able to get a message from the dbopen function when it fails. I think it should be possible when I look in a C manual for instance here, I see a errno get set.. but not sure how to retrieve it.

Any help would be apreaciated.

what are you trying to get out? Normally what you see in the dll file is what you can get out. PHP wouldn't hide stuff from you. I don't think it can be done....

If you see the mssql manual on MSDN you can see more about the dbopen function. Here you can see that the function can return 4 diffrent error codes.

SQLEMEM Unable to allocate sufficient memory.
SQLEDBPS Maximum number of DBPROCESS structures already allocated.
SQLECONN Unable to connect: SQL Server is unavailable or does not exist.
SQLEPWD Login incorrect.

But it seems in the php_mssql.c that when the dbopen fails it just returns the message "Unable to connect to server:" nomather what the error is. I woul like to get out the more spesific error message from the database driver.
